After receiving more than 165,000 emails from disgruntled customers in one day, Verizon rescinded its $2.00 a-month-fee to customers who paid their bills online or by phone. Similarly, Bank of America abandoned its $5 a-month-fee for debit cardholders after being inundated by emails from angry customers.

How did these consumer victories happen? In large part the credit goes to Change.org, a website that makes it easy to mobilize people to fight corporate greed or city hall.
